Common caffeine pointers advocate the consumption of 3-6 mg/kg of caffeine, sometimes 60 minutes earlier than the beginning of train.

For me, that’s 177 mg to about 350 mg. Nonetheless, there may be actually inter-individual variation in response to this standardized protocol. Some athletes are extra caffeine delicate than others. I personally, do not suppose I’d do properly with consuming 350 mg of caffeine earlier than train, as I’m extra caffeine delicate and that’s getting near the higher restrict of the beneficial quantity of caffeine per day, established by Well being Canada, which is 400 mg/day. The diploma of caffeine sensitivity/ tolerance could possibly be defined by genetic variations, associated to caffeine metabolism or adenosine receptor density.

Further analysis has discovered that reasonable to excessive caffeine doses (5–9 mg/kg physique mass (bm)), ingested earlier than and through train, elevated endurance efficiency in laboratory and discipline settings. These doses are related to elevated coronary heart charge and blood catecholamines, lactate, free fatty acid and glycerol ranges in lots of topics. Nonetheless, unwanted side effects that always happen embody gastrointestinal upset, nervousness, psychological confusion, lack of ability to focus and disturbed sleep.

Decrease caffeine doses (<3 mg/kg bm ~200 mg) taken earlier than, throughout and late in train additionally enhance endurance efficiency, and don't trigger the physiological modifications and unwanted side effects famous above in most people.

Analysis has demonstrated that caffeine has a small however evident impact on endurance efficiency when taken in reasonable doses (3–6 mg/kg) in addition to an total enchancment following caffeine in comparison with placebo in imply energy output and time-trial completion time.

It is usually doubtless useful to eat caffeine throughout a future or race. Higher responsiveness to small quantity of caffeine (2-3 mg/kg) could also be seen when it’s taken throughout a race, across the onset of fatigue.

I am normally consuming 25-100 mg of caffeine throughout my run.

I’ve been working and taking part in soccer for years, so I’ve been capable of experiment with completely different quantities of caffeine consumption earlier than and through train. I normally eat two cups of homebrewed espresso (~ 200 mg of caffeine) earlier than my run and earlier than soccer. As I’m presently coaching for a full marathon in Might, I do discover it’s useful to eat extra caffeine throughout my lengthy runs (that are 2 hours +). I’ll sometimes eat that caffeine within the type of power gels, that incorporates one other 100 mg of caffeine. This has helped scale back fatigue for me and helped with endurance throughout my lengthy runs.

Backside Line:

Caffeine is an efficient ergogenic acid throughout bodily exercise, serving to to scale back fatigue and improve efficiency. Nonetheless, it is very important be aware of caffeine consumption in order that we do not exceed the 400 mg/day or 300 mg throughout being pregnant.
